am i right in sayin its a 4 inch 50 caliber mark 9 gun its designed for. barrel has a bore of 4 inches and the barrel is 50 calibers therefor 4x50= 200 inch long barrel

ok ive found it the joys of wikipedia >>>The 4"/50 caliber Mark 9 gun (spoken "four-inch-fifty-caliber") was the standard low-angle, quick-firing gun for United States destroyers through World War I and the 1920s. United States naval gun terminology indicates the gun fired a projectile 4 inches (10 cm) in diameter, and the barrel was 50 calibers long. (barrel length is 4" x 50 = 200" or 5 meters)[1]

 

The gun weighed about 2.7 tonnes and used fixed ammunition (case and projectile handled as a single assembled unit) with a 14.5-pound (6.6 kg) charge of nitrocellulose propellant to give a 33-pound (15 kg) projectile a velocity of 2900 feet per second (884 m/s). Range was 9 miles (15 kilometers) at the maximum elevation of 20 degrees.[2]

 

Increasing awareness of the need for improved anti-aircraft protection encouraged mounting of dual purpose guns on destroyers beginning in the 1930s. The dual-purpose 5"/38 caliber gun became standard for United States destroyers constructed from the 1930s through World War II. United States destroyers built with 4"/50 caliber low-angle guns were rearmed with dual-purpose 3"/50 caliber guns. The 4"/50 caliber guns removed from destroyers were mounted on Defensively Equipped Merchant Ships like SS Stephen Hopkins

[mad al 146]

now I don't think I'd have posted a pic of any shell that came from any of the World Wars, or anything that belongs to the MOD but that's what you're looking at, surface to surface for sure, surface to air doubtful but ya never know.......... does it have any stamp on it that resembles a "crow's foot"?

[lgray88 4]

no stamps resembling a crows foot just the anchor symbol and theres also a capital R on one side of the bottom of the shell, whats the problem with posting a picture of this , you should see how much we trawl up when fishing my old man must be had about 3 to 400 shells some still live.
